On 18th September 2012, Microsoft released a temporary fix for a discovered software vulnerability. The security flaw in question allows the Poison Ivy Trojan to be installed on its browsers – and according to Microsoft’s website, nearly all versions are affected. This malware is capable of stealing data and taking remote control of PC’s, so it’s important to act fast.

If you’re an Internet Explorer user, the advice is to swap to another browser until a permanent software update is available (which should be in around a week).
